OK to Delete C:\ProgramData\. . .\Programs\Startup\SeaMonkey folder?

I ordinarily access SeaMonkey by using a Classic Shell © 2009-2014, Ivo Beltchev Start Menu. But somehow my 64-bit Windows 7sp1 laptop now has an additional SeaMonkey access location, at C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\SeaMonkey folder, which includes the following short cuts: SeaMonkey, SeaMonkey Mail, SeaMonkey (Safe Mode), and Profile Manager. These are identical to the contents in Classic Shell's Start Menu.

Sometimes these ProgramData shortcuts simply put a SeaMonkey item on my laptop's bottom location, but the item there simply says "SeaMonkey" (without the quotes) and does nothing, except to prevent my Classic Shell start menu from working.

I want to delete the C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\SeaMonkey folder (without deleting C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\, because it includes Bluetooth and Digital Line Detect shortcuts, and desktop.ini.)

Is there any any reason for me to NOT delete the C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\SeaMonkey folder?

I definitely need a knowledgeable answer to my question.

Those files you refeer too are precisely what feeds the start menu, that's why they're identical.
The start menu is actually filled with files from two locations:
-C:\ProgramData\Microsoft\Windows\Start Menu\.........
-C:\Users\<user>\AppData\Roaming\Microsoft\Windows\Start Menu\.........

The first being entries common to all users and the second for entries particular to the current user. The only thing the start menu does is displaying the contents of these two folders combined in a "nice" way. So, if you delete those files, the start menu will become empty too.

Classic Shell is irrelevant here. It's just an alternative UI for the very same functions, but otherwise it fetchs its entries in the same way.

Thanks to everyone for their help. Earlier today, at C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\SeaMonkey [a folder containing shortcuts to SeaMonkey, SeaMonkey (Safe Mode), SeaMonkey Mail, and Profile Manager], I deleted that folder (but not deleting anything else) by moving it to an external DVD disk in case I needed to restore it.

But so far, the computer is now using the Classic Shell © 2009-2014, Ivo Beltchev Start Menu to receive and send emails and visit websites with no problems.

I should make clear that the SeaMonkey folder that I have now deleted was an fairly large window (lots of white space) approximately in the center of my laptop's screen when I first turned on the computer. As a general rule (there were some mysterious exceptions) the taskbar didn't show anything new until I clicked one of the window's shortcuts.
Unfortunately, I don't know how to take a picture of what I have now described.
Note that I followed your advice to make a backup of the window, by not merely deleting it but instead moving it onto a DVD.

You wrote that

My laptop has only one human user, but there are three accounts: Administrator, AdminUser, and MereUser. And now the SeaMonkey folder that caused problems is now deleted (moved to a DVD). And the Classic Shell © 2009-2014, Ivo Beltchev Start Menu is now working without interference from the deleted (moved) folder is located in each account's folder:
C:\Users\Administrator\AppData\Roaming\Microsoft\Windows\Start Menu (rarely used).
C:\Users\AdminUser\AppData\Roaming\Microsoft\Windows\Start Menu.
C:\Users\MereUser\AppData\Roaming\Microsoft\Windows\Start Menu.

I hope that all of this makes sense. In a day or two later I will visit here to see if there are any additional comments or suggestions.

Thanks to everyone for all of your help.
I won't "Mark as Solved" until I have more experience with what I have done, probably later this week or early next week.
